[UPDATED] I have an asus u56e-bbl6 with an intel centrino wireless-n + wimax 6150 (rev 67) network controller. I installed 64-bit f16 using the live cd which was the 3.1.0-7 kernel. Wireless did not work but i finally resolved this problem with modprobe iwlagn bt_coex_active=0. Somehow (i guess a security update), the 3.2.7-1 kernel got installed. Wireless did not work using this kernel but i was able to resolve this with modprobe iwlwifi bt_coex_active=0. I then went ahead and did a full update to the system (~200 MB). Now wireless does not work with either kernel and i have no clue how to fix it. I've waited a couple of days to see if there were any further updates which might fix this but there have not been any.

I would really appreciate some help - thanks in advance -

I got frustrated and completely reinstalled using the live CD and then did a complete update. The update installed the 3.2.7-1 kernel. I have had no luck getting the wireless to connect. Network manager does show that i can enable/disable wireless with the function key. Below is the output of some of lspci, rfkill, iwconfig and some of dmesg. I am currently using the 3.2.7 kernel with bt_coex_active=0. Please let me know if you have any ideas - i'm a little surprised that i have not been able to solve this by searching the web or with the help from someone on this forum. Thanks -

I have the same laptop model as yourself, and I have had the same problem. I had initially been running F16 with XFCE, and tried installing from live LXDE, which I'm currently using. I can still use wireless, but only by chosing to go with the 3.1 kernel that's still in the GRUB boot menu. In that situation, the iwl.conf fix still works. Oddly enough, 3.2.7-1 worked with the fix when I was using XFCE.

I'm still a relative Linux newb, but some poking around has found similar issues with Debian and updating to kernel 3.2.7-1. And, being a newb, it still takes me a while to figure out what's going on. Until someone smarter comes along, I'll be stuck with the old kernel.

Here's what I figured out: I ran lspci -v to see what driver was being used for wireless. At least with kernel 3.2.9-2, the kernel driver for wireless was iwlwifi, whereas before the kernel was using iwlagn. I simply adjusted etc/modprobe.d/iwl.conf to read: options iwlwifi bt_coex_active=0, changing iwlagn to iwlwifi. Reboot. Wireless works.
